JL Audio AP300/4 Compact Marine Amplifier 4 Channels, 300W
Power the moment with the ultracompact JL Audio AP amplifiers, available in monoblock, 4 channel with and without Bluetooth technology, as well as 6 channel with staggered power — ideal for a system amplifier. These Class-D amplifiers are IP67-rated (excluding cables) with tough cast-alloy water-resistant construction.
The monoblock, 4 channel and 6 channel feature built-in LCD displays for manual control. For additional optimisation, pair with a Fusion head unit with built-in DSP, and download the Fusion Audio smartphone app for selectable profiles. This enables the Easy Tune feature, which streamlines amplifier setup to ensure superior sound quality and system protection.
The 4 channel with Bluetooth pairs with your smartphone for seamless audio streaming and includes an IP67-rated wired remote that can be flush-, surface- or bar-mounted.
